- DAO Supplements Histamine Blocker – Advanced DAO Enzyme Formula and Vitamin C for Histamine Digest & Intolerance Support – Diamine Oxidase DAO Supplement, 30 Capsules

I am allergic to so much stuff this was recommended from a co worker... I was surprised, rash went away and no other issues. Was very pleased it worked

I’ve noticed a big difference since starting this supplement. It helps reduce reactions from certain foods and supports better digestion. Easy to take and gentle on the stomach! great quality and worth it!

Not worth the money for the amount but it does work

If you are like me, you are taking a multitude of medications and supplements to treat your MCAS/POTS/Dysautonomia/ETC. It has become clear this disease effects people differently which is why it is so difficult to find a one size fits all plan for recovery. Adding to this, what works one month may not work the next bc your symptoms change very quickly. What I can say about this product is before I started taking my current regimen of medications and supplements, I could not eat 99% of the things I attempt to digest. It has been like this for almost a decade. I started taking this supplement and Cromolyn, and now I can eat about 80% of the things I want. Yes. I cried. Alot. How do I know it is because of this supplement and this supplement alone? I think at this point it would be foolish for any of us to think after years of suffering, it is only going to take one little pill to make us normal. IDT we will ever know what normal is ever again. I can say that I am confident that this supplement is a part of a regimen that works for me that has enabled me to eat pizza at night with my wife as we watch Game of Thrones (she hasn't seen it yet - so no spoilers! :) I ran out this week and with it being Christmas week, I got behind on re-ordering so I haven't taken it this week and I have thrown up my dinner twice sooooo using that data, one can extrapolate that with the supplement I am able to keep pizza down. Without it, I vomit. Needless to say, I am re-upping. I did not have any side effects taking this supplement daily for a month. All I felt was a increase in health benefits ranging from increased food choice to less exhaustion.

Helped me minimize the effect of high histamine foods, but not as effectively as other DAO enzymes I’ve tried.

This DAO supplement has really helped support my digestion when eating foods that typically trigger histamine reactions.

I've only taken this a few times and have had what seems to be an allergic reaction every time I've taken this. And thats with opening the capsule and only taking 1/4-1/2 of a serving. I finally had to stop and research why this would be happening with a product that should be reducing allergic reactions! I started looking at the reviews and seeing that this is sourced from pork, which I am allergic to. Is this true? If so, it should be stated. Either way, the source of the supplement should be stated. For someone experiencing extreme histamine symptoms, this is awful to go through. The seller has a 365 day return window yet amazon says I can't return it. So I'm on here writing a review hoping the seller will make it right since I have no other way to contact them.

I have had issues with my gut for years. I came across this product and thought I would give it a shot as usually I just have to take tums and spend hours in the bathroom. I have had to narrow down my diet to chicken and rice because how so many good upset my stomach, I missed the flavors as I love to cook. I enjoy trying new foods but because of my gut I am so skeptical about what I eat and have a huge debate if it will be worth spending 4/8 hrs in the bathroom. After finding this product I was really skeptical if it would really help me. I was willing to give it a shot because why not. I figured worst case it didn’t work and I was back to where I was before I started it. It has been a month since I started and let me tell you, it is going great! The pills are flavorless and the go down so easy, (I also have an issue swallowing pills). My life is getting better. I can enjoy foods I once was so scared to eat because it was a huge debate. Now I just take a pill and eat my food and enjoy the rest of the day. I can now go out and try more new foods with my spouse and it is great! We have started a bucket list of food places we want to try now I don’t have to worry. This product is definitely worth the money!

Me lo tomo y noto una disminución de loa síntomas, es mejor si se toma en la noche

No me sirvió. Realmente no me ayudó e incluso mis síntomas intestinales fueron peores a lo habitual, mucho gas, ardor y diarrea líquida. No lo recomiendo
